'r s PATENT OF IC FRANK BENNETT, or nnLivrAn, NEW YORK.

FLOUR-SIFTER.

To all whom it may concern:

Be it known that I, FRANK BENNETT, a citizen of the United States, and aresident of Delmar, in the county of Albany and State of New York, haveinvented a new and Improved Flour-Sifter, of which the following is afull, clear, and exact description.

This invention relates to kitchen utensils, and has particular referenceto flour sifters.

Among the objects of the invention is to provide a device of thecharacter set forth of a simple and cheap construction and adapted for arapid sifting operation.

The foregoing and other objects of the invention will hereinafter bemore fully described and claimed and illustrated in the drawings forminga part of this specification in which like characters of referenceindicate corresponding parts in all the views, and in which- Figure 1 isa perspective view showing a preferred form of my invention; Fig. 2 is avertical sectional view of the same; and Fig. 3 is a plan view of therotary member and its support detached from the shell.

The several parts of this device may be made of any suitable materials,and the relative sizes and proportions, as well as the general design ofthe mechanism, may be varied to a considerable extent without departingfrom the spirit of the invention hereinafter more fully described andspecifically claimed.

Referring more particularly to the drawings, I show at 10 a shellpreferably of cylindrical form having an open top and a bottom open butfor a flange 11 secured thereto in any suitable manner, said flangebeing inclined downwardly slightly toward the vertical axis of thedevice.

At 12 I show a screen or agitating member of peculiar form andconstruction fitted within the shell 10 and resting normally upon theupper surface of the flange 11. Said agitator 12 comprises an upwardlycurved screen 13 preferably in the form of a hemisphere whose diameteris substantially equal to the inner diameter of the shell. Said screenis secured to and supported by-a peculiar construction of frameworkcomprising an annular base 1 1 and a pair of bows 15 connected at theirlower ends to the annulus 141 and crossing each other in the verticalaxis of the agitator.

Specification of Letters Patent.

Patented Jan. 12, 1915. Application filed July 8, 1914. Serial no,849,722.

This framework constitutes a-reliable sup- 7 port or binder for both thelower edge of the screen andthe dome portion thereof in practical use.-The screen may be made of any suitable material such, for instance, as awire netting. The agitator includes also some suitable means connectedto the screen for rotating the same either continuously or otherwise. Asshown, I provide a shaft 16 provided at its upper end with a crank 17and secured rigidly at .its lower end by means of nuts 18 or the like tothe screen and supporting bows 15. Any suitable means may be providedfor maintaining the shaft 16 coincident with the vertical axis of' theshell 10. For this purpose I prefer to use a yoke 19 having a bearing 20in the center and having its ends bent downwardly, as shown at 21, anddetachably connected with a series of ears 22 formed by thecircumferential slits 23 in the side walls of the shell. This yokestructure andmeans for supporting it are not onlysimple and reliable inconstruction, but provide for the easy removability of the yoke for thepurpose of removing the agitator from the shell.

I have found by experiment that a flour sifter made in accordance. withthe disclosure herein is much more effective and I claim as new anddesire to secure by Letters Patent I 1. In a flour sifter, thecombination of a substantially cylindrical shell having acircumferential flange secured to the lower edge thereof, the flangeprojecting inwardly toward the vertical axis of the shell, a hemispherical upwardly arched screen supported with its open edge upon saidflange, and means connected to said screen to maintain it in the formindicated and to rotate it upon said flange, substantially as set forth.

2. In a flour sifter, the combination of a shell, an annular flangesecured to the lower end of the shell, said flange projecting inwardlytoward and inclined downwardly with respect to the central axis of theshell, an agitator within the "shell comprisingan annular base, a pairof semi-circular'bows connected at their lower ends to said base andextending upwardly and across each other at the central axis of theshell, and a hemispherical screen above and connected to said annularbase and bows, said agitator being mounted for rotation upon saidflange, 10 and means to rotate the agitator.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

FRANK BENNETT.
